CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 16/943,962, filed Jul. 30, 2020, which claims priority to U.S. Provisional Patent Application No. 62/880,589, filed Jul. 30, 2019, the disclosures of which are hereby incorporated by reference in their entireties.

FIELD

The present disclosure relates to handheld exercise weights, and more particularly to handheld weights having specific ergonomic shapes that allow for the weight to be distributed in and across the hand during physical activities, such as exercise or more importantly training. Moreover, this present disclosure identifies specific advantages of having a handheld weight that not only conforms to the natural shape or grip of the hand but has a specific weight distribution across the hand to achieve a desired sports or athletic technique through positive torque during training exercises, drills, or functional movements.

BACKGROUND

Sports training and coaching has always been an effective way to teach a philosophy, technique, or an athletic trait to an athlete in order to achieve and maintain physical prowess and success. Across all sports, coaches and trainers instill valuable techniques that enable athletes to move their bodies in response to stimuli or to properly achieve a maximum effort towards a specific goal or feat.

Weights or other resistance training devices are often used by coaches or trainers to create physical exertion levels above and beyond what the body experiences in sports to make the athlete stronger, faster, or more physically fit. However, many athletes need additional specialized tools to absorb the proper technique and or improve athletic form or performance. Muscle memory also plays a key role in the athlete developing proper form or technique during sports. Adjustments or tweaks to an athlete's form or technique is often needed to unleash the true potential of the individual. Tools or techniques that teach positive muscle memory to athletes are becoming increasingly important factors in achieving success at the highest levels of sports.

Current weights or standard resistance systems may not be as advantageous as originally thought due to the creation of poor muscle memory from torque or improper weight distribution of the tool or device. For example, current dumbbell has been viewed as a great tool for building up strength, speed, and endurance for boxing training; however, on closer examination the weight distribution creates a negative torque on the wrists and elbows resulting in poor form and technique. The use of these current dumbbells can even cause injury to joints and connective tissue over time. The same can be true across many other sports including track and field events, long distance running, golf, hockey, baseball, basketball, football and many other hand and eye coordination sports.

Therefore, there exists a need for handheld weights having specific ergonomic shapes that allow for the weight to be distributed in and across the hand during physical activities, such as exercise or more importantly training. Moreover, this present disclosure identifies specific advantages of having a handheld weight that not only conforms to the natural shape or grip of the hand but has a specific weight distribution across the hand to achieve a desired sports or athletic technique through positive torque during training exercises, drills, or functional movements.

SUMMARY

Provided herein are example embodiments of systems, devices and methods to provide handheld weights having specific ergonomic shapes that allow for the weight to be distributed in and across the hand during physical activities, such as exercise or more importantly training, such as sports training. Moreover, this present disclosure identifies specific advantages of having a handheld weight that not only conforms to the natural shape or grip of the hand but has a specific weight distribution across the hand to achieve a desired sports or athletic technique through positive torque during training exercises, drills, or functional movements. The small light weight unit can be securely held in the hand during sports training to properly teach technique, form, and development of correct muscle memory over time with less risk of injury.

Generally, the present disclosure provides an exercise weight unit that when held by a user may create a positive effect on Muscle Memory Training. Muscle Memory Training can be defined as specific repetitive movements or techniques used to engrain a preferred or desired motion or combined motions or physical output of an athlete.

In some embodiments, the present disclosure may include an exercise weight unit adapted to be handheld and palm-centered, comprising: a body having first and second ends, a central portion, and a central axis between the first and second ends; and a feature at an end of the body configured to create a slight inward torque when the weight unit is held in a hand of a user during physical sports training, wherein the feature is one of a hook shape, a “mushroom” shape and a “fin” shape.

In some embodiments, the weight unit may be in a rounded or oval shape. In some embodiments, the weight unit may include a partial protrusion (“fin” or “hump”) extending from one end of the oval shape to the other end. In some embodiments, the weight unit may include a “mushroom” head or “hook” shaped end extending inward or over the index finger and or thumb. These partial protrusions (“fins” or “humps”) may be located on the weight unit itself to add additional torque across the mid-line of the weight making it slighted off balanced when held in the hand. The “mushroom” head or “hook” feature are located on the outside of the weight unit, more specifically at the inward body facing end, near the thumb and index finger, or forefinger. These weight features may create a slight inward torque when held during physical sports training. This torque effect may be critical to develop proper muscle memory in many sports movements and techniques.

DETAILED DESCRIPTION

The following disclosure describes various embodiments of the present invention and method of use in at least one of its preferred, best mode embodiment, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications to what is described herein without departing from its spirit and scope. While this invention is susceptible to different embodiments in different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated. All features, elements, components, functions, and steps described with respect to any embodiment provided herein are intended to be freely combinable and substitutable with those from any other embodiment unless otherwise stated. Therefore, it should be understood that what is illustrated is set forth only for the purposes of example and should not be taken as a limitation on the scope of the present invention.

In the following description and in the figures, like elements are identified with like reference numerals. The use of “e.g.,” “etc.,” and “or” indicates non-exclusive alternatives without limitation, unless otherwise noted. The use of “including” or “includes” means “including, but not limited to,” or “includes, but not limited to,” unless otherwise noted.

As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including entities other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like.

As used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

In general, terms such as “coupled to,” and “configured for coupling to,” and “secure to,” and “configured for securing to” and “in communication with” (for example, a first component is “coupled to” or “is configured for coupling to” or is “configured for securing to” or is “in communication with” a second component) are used herein to indicate a structural, functional, mechanical, electrical, signal, optical, magnetic, electromagnetic, ionic or fluidic relationship between two or more components or elements. As such, the fact that one component is said to be in communication with a second component is not intended to exclude the possibility that additional components may be present between, and/or operatively associated or engaged with, the first and second components.

Provided herein are example embodiments of systems, devices and methods to provide handheld weights having specific ergonomic shapes that allow for the weight to be distributed in and across the hand during physical activities, such as exercise or more importantly training, such as sports training. Moreover, this present disclosure identifies specific advantages of having a handheld weight that not only conforms to the natural shape or grip of the hand but has a specific weight distribution across the hand to achieve a desired sports or athletic technique through positive torque during training exercises, drills, or functional movements. The small light weight unit can be securely held in the hand during sports training to properly teach technique, form, and development of correct muscle memory over time with less risk of injury.

The present disclosure provides an exercise weight unit that when held by a user may create a positive effect on Muscle Memory Training. Muscle Memory Training can be defined as specific repetitive movements or techniques used to engrain a preferred or desired motion or combined motions or physical output of an athlete.

In some embodiments, the handheld weight unit of the present disclosure may create a slight inward torque when held during physical sports training. This torque effect may be critical to develop proper muscle memory in many sports movements and techniques.

Some handheld weight units were previously described in related applications, such as U.S. Non-Provisional application Ser. No. 15/188,048 filed Jun. 21, 2016, U.S. Appl. No. 62/682,707, filed Jun. 8, 2018, and PCT Application No. PCT/US2019/035886 filed Jun. 6, 2019, the entire contents and disclosures of which are hereby incorporated by reference. These and the lightweight handheld weight units of the present disclosure do not change relative physical size as they increase in weight with the change of the materials (e.g., metals) used. For example, denser and denser metals may be used to keep the weight size and shape consistent with the shapes outlined and described even as the weight is increased. For example, the weight range can vary from 0.5 to 5 pounds and remain a valuable training tool without obstructing fluid motion. Metals used may be cast iron, stainless steel, bismuth, tungsten alloys, and pure tungsten. But other suitable materials may also be contemplated.

In some embodiments, the weight unit may be in a rounded or oval shape. In some embodiments, the weight unit may include a partial protrusion (“fin” or “hump”) extending from one end of the oval shape to the other end. In some embodiments, the weight unit may include a “mushroom” head or “hook” shaped end extending inward or over the index finger and or thumb. These partial protrusions (“fins” or “humps”) may be located on the weight unit itself to add additional torque across the mid-line of the weight making it slighted off balanced when held in the hand. The “mushroom” head or “hook” feature are located on the outside of the weight unit, more specifically at the inward body facing end, near the thumb and index finger, or forefinger. These weight features may create a slight inward torque when held during physical sports training. This torque effect may be critical to develop proper muscle memory in many sports movements and techniques.

Turning now to the figures, FIGS. 1A to 1C illustrate exemplary perspective views of 3 exercise weight units, according to some embodiments of the present disclosure. In some embodiments, the present disclosure may provide a small light weight unit in a rounded or oval shape main body 114, 124, 134. In some embodiments, as shown in FIG. 1A, a “hook” feature 114 may protrude at one top or in the vicinity of one top of the body 112 of the weight unit. The hook feature 114 may be positioned on the inner most side of the weight unit when held. In some exemplary uses, as shown in FIG. 2C, the hook feature 114 may be positioned over the thumb or index finger when held by a hand. This protruding weight hook feature 114 may follow the contours of a hand when held by the hand, more particularly the thumb or index finger of a closed or soft closed fist, to add additional weight on the inside of the hand and across the mid or center line of the hand (see center line C in FIG. 3C).

In some embodiments, as shown in FIG. 1B, the present disclosure may provide a small light weight unit in a rounded or oval shape main body 122 with a “mushroom” head feature 124 protruding at an end of the body 122. This protruding weight “mushroom” head feature 124, when held by a hand, may follow the contours of the hand, more particularly the opening of the hand when in a closed or soft fist, to add additional weight on the inside of the first and across the mid or center line of the hand (see center line C in FIG. 3C).

In some embodiments, the “mushroom” feature 124 may protrude at one top of the body 122 at one end of the weight unit. In some embodiments, the mushroom feature 124 may have a substantially circular flat top. In some embodiments, the flat top may slightly slope outwardly toward the body 122.

In some embodiments, as shown in FIG. 1C, the present disclosure may provide a small light weight unit in a rounded or oval shape main body 132 with a partial protruding “fin” or “hump” feature 134 at an end of the weight unit. This protruding weight fin” or “hump” feature 134 may follow the contours of a hand, when held by the hand, more particularly the open space or gap in the palm when the hand is closed around the weight unit and provides additional weight on the inside of the hand and across the mid or center line of the hand (see center line C in FIG. 3C).

In some embodiments, the partial protrusion (“fin” or “hump”) feature 134 may protrude from the body 132 and located toward one end of the weight unit.

In some embodiments, the unique shape of the weight unit may be combined with a natural secure finger loop grip to make the weight unit a unique and advantageous tool. This unique and advantageous feature is particularly useful in Muscle Memory Training and/or developing proper form or technique.

FIG. 2A illustrates a handheld exercise weight unit 200, according to some embodiments of the disclosure. In some embodiments, the handheld exercise weight unit 200 may include a rounded egg or oval shaped weight unit main body 202, and a finger loop grip strap 204 that may be removably affixed to the weight unit main body 202. In some embodiments, the main body 202 may include two drill holes 210 and 212 such that the strap 204 may be affixed to the main body 202 by screws 220 through elongated openings 230 and 232. The elongated openings 230 and 232 allow the strap 204 to be adjustable. In some embodiments, the finger loop grip strap 204 may be made of leather. In some embodiments, the finger loop grip strap 204 may be made of other suitable material.

FIG. 2B illustrates an exemplary assembly of the handheld exercise weight unit 200 with the finger loop grip strap 204, according to some embodiments of the disclosure. The elongated openings 230 and 232 may slide along the corresponding drill holes 210 and 212, before the strap 204 being secured to the main body 202, to allow a desired height H to fit a finger of a user. This desired height allows a custom fit to each user's finger size.

In some embodiments, the strap 204 may be affixed to the main body 202 by any other suitable mechanism that allows the strap 204 to remain secured to the main body 202 while the strap 204 holds a finger of a user during an exercise.

Although FIGS. 2A and 2B show the weight unit 200 without a hook feature, or a mushroom feature, or a fin or hump feature shown in FIGS. 1A to 1C, or an arc shape protrusion, the weight unit 200 may also include one of these features as disclosed above.

FIGS. 3A to 3C illustrate an exemplary use of the torque generating weight unit of the present disclosure. In this example, the weight unit 100 of FIG. 1A is shown, but other weight units, e.g., as shown in FIGS. 1B and 1C may also be applicable. FIG. 3A shows an exemplary hand 300 in a closed or soft fist condition or position, without using the weight unit. FIG. 3B shows the weight unit 100 with the main body 112 and the hook feature 114. FIG. 3C shows the weight unit 100 being held within the hand 300 fist, where the hook feature 114 may be positioned over the thumb or index finger, being to the right of the center line C of the fist. This protruding weight hook feature 114 may follow the contours of the thumb or index finger of the closed or soft closed fist.

In the example of FIG. 3C, the weight unit also includes a finger loop grip strap 204, which loops around the middle finger of the hand. The unique finger loop grip strap 204 may secure the weight unit to the hand at the center most point C of the fist allowing for a secure confident hold. The extra torque generating “hook” feature 114 pictured here at roughly 12 percent of the total weight creates enough pull to turn the wrist slightly inward toward the body during physical activity or at rest.

In some exemplary uses, the weight unit may advantageously be used in the “corkscrew punch” training. In the “corkscrew punch”, the modern punching technique for boxers or mixed martial arts fighters, the fist rotates inwards as the arm extends so that the palm is facing down or “turned over” when the fist lands. This punch was said to be invented by a famous boxer named Charles “Kid” McCoy who (fought from 1891-1916) and learned the technique by watching a cat strike at a ball of string. McCoy imitated this corkscrew motion to add power to the punch and cut the opponent's skin. Being that he was wildly successful and known to be one of the great punchers of all time, his punching technique became famous. Over the years, many fighters and practitioners of different martial arts have made similar discoveries resulting in differing variations of the “corkscrew punch”. What remains the same is that a corkscrew punch thrown with a wrist rotation, or inward rotating thumb.

In some exemplary uses, the partial protrusion (“fin” or “hump”), “mushroom” head or “hook” feature on the inner most side of the weight unit would be advantageous, for example, in long distance running. Unlike sprinting or max exertion running, long distance running is about being relaxed and exerting the least amount of energy possible to sustain a desired lasting pace. There are many differing philosophies of long distance running, however, most experts can agree on several key positive techniques: (1) a natural forward lean, (2) mid foot strike, (3) relaxed/open shoulders for breathing, (4) arm swing from the shoulder at a 90-degree angle, (5) an open/soft hand, (6) forward looking head, (8) activated core for hip alignment, (9) stride mobility with a strong leg kick, and (10) inward forward arm drive.

The above are exemplary important aspects of proper running form that are entwined, and one can negatively affect the others if not done correctly. Identifying a negative aspect of an individual's running form can be difficult unless under professional supervision, and at times it can be even more difficult to correct if the negative form cannot be measured or felt by the runner. By using an inward weighted torque generating training tool of the present disclosure, a runner can instantly feel the effects of poor running form. Poor running mechanics are identified to the runner as the torque generating weights naturally exaggerates the negative movements. Expert running coaches or trainers use the term, “you must run slow to run fast.” What they are trying to convey is the notion that an individual must be able to feel proper running form even at a slow pace to develop proper muscle memory when running fast. The present disclosure provides this capability and is described further below.

Several examples of how a lightweight torque generating hand weight of the present disclosure can advantageously identify and correct poor running form include:

(1) Striking the foot on the ground at the heel or toe is considered a symptom of poor running form and can often create injuries due to the force of impact. In these examples, the body is either too forward leaning or too far back or upright during running. By using the handheld weight unit of the present disclosure as training tool, the issue either resolves as the weight pulls the body forward into alignment or exasperates the poor form by driving the body even more forward.

Alternating running with and without the hand weights is a quick way to identify the positive or negative impact of the weight and for making positive adjustments to running form.

(2) Relaxed or “Open” shoulders result in the natural opening of airways making it easier to breath during long distance running. Conversely, if the shoulders are rolled forward and tight it becomes harder to breath during running and a natural arm swing becomes inconsistent and tight. Additionally, if shoulders are too far back the body leans backwards and effects the above stated foot strike.

(3) While running, a strong engaged core creates tension in a runner's mid-section and central posture resulting in the amount of power and strength generated from the legs, hips, glutes, etc. to drive the body forward. The positive generating torque weights activate the core while the weights are swung naturally or extended outward and inward from the body. This technique helps the runner identify the level of core activation and intensity needed to properly drive the body forward.

The torque generating weight unit of the present disclosure may advantageously identify poor running techniques or form over time. These weight units add intensity to the exercise and also identify imbalance and lack of muscular engagement. In other words, the weight units are both an intensifier but also a tool for proper technique. In some embodiments, alternating running with and without the handheld weight units may be a quick way to identify the positive or negative impact of the weight and for making positive adjustments to running form.

Additionally, running or training with the handheld weight units will increase core strength with proper functional and fluid motion. Other core strengthening exercises such as sit-ups or planks are great at strengthening the body's center, but they do not strengthen core muscles while the body is in an active running motion.

Strengthening or conditioning the body's core muscles during running is key to endure long distance running. Over time core muscles can become weak or tired resulting in poor overall running form. The core is the connective center that aligns the body during running and a weak core is often the culprit of poor running form over long distances.

Additionally, the lightweight inward torque generating weights may be ergonomically shaped to match the natural soft/open grip of the running hand and running form. The weights may pull hands and elbows close to the body without the risk of hitting the runner's body during motion unlike a dumbbell. This pulling of the hands and elbows inward close to the ribcage may help to create the most efficient running form—an inward and upwards arc towards the chest as the arms swing.

This natural arm motion is a key starting or launching point to evaluating a runner's overall form, performance, and timing. Learning to run efficiently with the lightweight hand weights creates proper form and muscle memory over time as the runner can adjust form but also weight intensity as they advance in skill.

Some exemplary benefits of these weighted shapes or features may include providing additional weight generating torque on the inside of the hand or closed fist during sports specific training. The additional weight shapes can range from 5-30 percent of the overall weight unit and is intended to naturally twist the hand inward during training exercises or motion but not prevent the hand from returning to its natural functional movement. The ideal range for the additional weight may be from 10-18 percent or roughly 2.0 ounces to 6.0 ounces depending on weight increment. Having too much weight generating torque on the hand can be detrimental to joints and connective tissue so the lesser the amount of weight needed to create positive muscle memory the better.

FIGS. 4A to 4D illustrate several exemplary perspective views of a “corkscrew” punch 410 aided by the held weight unit with the “hook” feature of the present disclosure. From a standard or beginning position 410, the hand is twisted inward and down, as shown in position 411 in FIG. 4B, then position 412 in FIG. 4C, and finally position 413 in FIG. 4D at the point of impact. The handheld torque generating weight unit may pull the weight down and inward as the punch is thrown, triggering positive muscle memory. After the point of impact, the arm may recoil back into the starting position or into another boxing scenario. The “hook” weight unit may create resistance and intensity throughout the entire desired motion making the fighter a faster and stronger puncher overall.

FIGS. 5A to 5C illustrate several exemplary perspective views of a closed soft running fist 500 depicted being open in FIG. 5A. FIG. 5B illustrates the soft hand fist 500 holding a torque generating weight unit 512 with “mushroom” head torque weight 120. FIG. 5C illustrates the soft hand fist 500 holding a torque generating weight unit 100 with “hook” torque weight 518.

These exemplary views demonstrate how the weight units may be held naturally in the hand with the weight unit on the inside of the fist towards the thumb and index finger. Not pictured is how they may help to drive the hands inward and upward during training. This forward arm swing or arm drive is critical in the development of proper running technique and form across the entire body.

The knob insert 1412 is a head element accessory that may releasably connect to and end of the body 1310. The knob insert may include a plurality of lock balls 1414. When the jump rope assembly 1320 is fully connected to the knob insert 1412, the lock balls 1414 engage corresponding indentations (or holes) on the inside wall of the quick release lock 1322, as shown in FIG. 14B.

FIG. 14C shows the quick release lock 1322 is in the disconnected state from the knob insert 1412, thus the jump rope assembly 1320 is disconnected from the handheld exercise weight unit's body 1310.

The above embodiments illustrate exemplary head elements and assemblies that may releasably connect to the handheld exercise weight unit. The configuration of the handheld exercise weight unit and other head elements and assemblies is advantageously flexible. Other head elements may also connect to the handheld exercise weight unit. Other attachable head elements and assemblies may include, for example, ring to attach other component (e.g., cable, hook, etc.), exercise band, gym cable, etc.

The advantages of being able to attach different head elements and assemblies are numerous. For example, the addition of an exercise band when added with an end weight collar or torque weight may allow for the tension and counterweight to be offsetting. This system of having a counter torque weight and exercise tension band on opposite sides of the hand creates greater stability and balance during exercise. This is critical in activating different muscle groups than a traditional linear exercise band held across the hand or held via a metal or plastic tube with equal tension being distributed across the hand. In addition, by alternating the end collar or torque weight on either side of the hand, a user can target the opposite sides of each muscle group during specific exercises. For example, with the band on the inside of the thumb and the counter torque weight on the opposite end of the hand during a bicep curl, the exercise targets the inside or front bicep as the weight and band are lifted. The opposite is true when the weight and band are switched. The weight may create a torque that shakes the hand and require more muscle activated to hold it steady during a specific motion, like a bicep curl. Alternating them activates the other muscle groups on the other side of the hand. The ability to target different muscle zones and the surrounding small muscle groups and stabilizing muscles by using the torque generating weighted end and an exercise band is critical for improving speed, strength and power for sports training that requires physical exertion in a nonlinear or straight line. Activating muscles from many differing angles and types of tension and intensity is what makes this exemplary system of the present disclosure a huge advancement in band and weight training. This system combines weight training, and band exercises with, for example: altering weight distribution, angle, tension side of the hand, and core stability.

Addition of the exercise band and others may provide a highly specialized sports training tool that can be used by professional or amateur athletes and coaches to replicate sports specific movements at a higher degree of difficulty and muscle activation.

In some embodiments, the present disclosure may provide a RFID tracking tag/microchip or other tracking device or system thereof which is embedded within a weight unit that communicates to a device, for example, a smart phone, smart watch, or similar device to automatically identify the individual or combined continuous weight values during upper body movements and/or exercise.

In some embodiments, the weight units may have a weight shell with varying insert weights that may be locked therein or removed to increase or decrease weight accordingly during physical activities.

In some embodiments, the present disclosure may include motion tracking sensors such as gyroscopes and accelerators within the weight units, a smart watch, or other monitoring devices that are worn on the wrist or forearm in combination with inputs from the user (e.g., height) to track individual upper body motion of the user through algorithms computing the X, Y, Z axis points (roll, pitch, and yaw), and rotational acceleration data points of each movement performed by the user.

In some embodiments, the data collected from the gyroscope and accelerator unit, in conjunction with the continuous held weight values, be visible to the user either on a smart monitoring device or uploaded to a smart phone, tablet, laptop, or computer in such a way that it is easy to read and understand. Such a format would include graphs, charts, total arm movements by category and muscle group, total pounds lifted per hour, total pounds lifted, total pounds lifted per muscle group, total pounds lifted per individual exercise, etc. In some embodiments, the total data generated from the gyroscope and the accelerator, in conjunction with the varying held weight, shall provide an overall analysis displayed on either the smart monitoring device itself or uploaded to a laptop, tablet, phone, or computer depicting an animated male or female digital body display with the intensity of the exercises and the muscle groups used to perform said exercises identified by color of intensity and performance. For example, if an individual performed mostly all bicep curls during their aerobic activity, the digital body would show red in the bicep muscle for high intensity, yellow in the forearm muscle group for medium intensity, and green for low performance or intensity in the remaining upper body muscle groups. Furthermore, by rotating the digital body with the swipe of a finger on the display window, the digital body rotates to show muscle groups located on the individual's back to complete the entire upper body muscle groups. The digital body may also include lower body muscle groups, utilizing data generated from the sensors to track muscle activity during aerobic exercise such as walking, jogging, running, running stairs, or hiking, etc.
